Morphology, morphometry and growth rings of the otoliths: sagitta, asteriscus and lapillus of Centropomus nigrescens Günther 1864 in Manzanillo and Santiago bays in, Colima, Mexico were studied. Differences between sexes, as right and left of the three pairs of otoliths were analyzed. In all cases the growth of the otoliths is eccentric to the core. Relationship between fish length and length and width of the otoliths showed that these structures have a negative allometric index. Twelve growth rings were identified in sagittae and asterisci. Growth rings could not be observed in lapilli because the thickness of this structure prevents the observation by transparency. Data on sagittae of C. undecimalis were compared with the present results.
